DNA sequences from the interphotoreceptor retinoid binding protein gene (Rbp3) in pocket gophers (Geomys) display an unusually slow rate of molecular evolution relative to other species of rodents. Rates of molecular evolution were examined in pocket gophers and other members of the rodent superfamily Geomyoidea to determine if this phenomenon was restricted to pocket gophers. DNA sequences from the Rbp3, mitochondrial 12S ribosomal RNA (12S rRNA), and mitochondrial cytochrome-b (Cytb) genes were compared within members of Geomys, among members of the Geomyidae, and among members of the Geomyoidea to ascertain rates of molecular evolution for the three genes among the various taxa. A variety of analyses (genetic distance, Tajima's relative rate test, Tajima's neutrality test, coalescence theory, and Hudson, Kreitman, and Aguad© test) indicated that DNA sequences affiliated with Rbp3 in species of Geomys were evolving at a rate slower than were sequences of members of the Heteromyidae. In addition, there was weak evidence suggesting that the Rbp3 gene in other pocket gopher genera (Cratogeomys, Orthogeomys, Pappogeomys, and Thomomys) evolved more slowly than in members of the Heteromyidae
